What is the most important characteristic of a fixed cantilever bridge?

The most important characteristic of a fixed cantilever bridge is that it is non-removable. A fixed cantilever bridge is designed to be permanently affixed to the supporting teeth or implants, providing stability and support for the prosthetic segment. This non-removable feature is critical because it ensures that the bridge remains securely in place, allowing for functional and aesthetic benefits over time, as it withstands the forces encountered during normal use, such as chewing and speaking.

In contrast, removable options do not offer the same level of stability and require active removal by the patient for cleaning or other purposes. Tooth movement is not relevant in this context since a fixed cantilever bridge is meant to maintain the alignment of the opposing teeth without allowing for any movement. Moreover, while a fixed cantilever bridge may require less space in some designs compared to other types of bridges, the key defining feature that sets it apart is its non-removable nature, which emphasizes its importance in restorative dentistry.
